MEASU'RING DEVICE FOR ARTESIAN WELLS.

SECIFICATION forming part of Letters Patent No. 706,438, dated August 5, 1902. Application led October 16,1901. Serial No. 78,857. (No model.)

To all whom, it may cmtcern: Beit known that I, SAMUEL MCCAUGHTRY,

a citizen of the United StatesofAmerica, residing at Washington, in the county of Washington and State of Pennsylvania,fhave in-` drilling of such Wellsit is often desirable to' determine the exact depth of the well. This has heretofore been a difficult matter, as the exact depth could only be approximated.

The object of my invention is to construct a device which is adapted to be applied to a A rope or cable asbeing withdrawn from the well, and this rope or cable actuates thedrivin g-wheel to operate the register or indicator, the latter being of any approved form.

Briefly described, my invention comprisesV a handle'for holding the device with a shaft journaled in this support for the handle and Aoperatively connected to an indicator or registering device, a drive-Wheel mounted on the shaft, and a pulley-wheel mounted in alinement with the drivewheeland having its supporting-bracket connected by a spring or like means to the main support, so that the pulley-wheeliSnOrmally heldagainst the drive-wheel, and when therope or cable is placed between the two wheels the tension of the spring is against the pulley-wheel, so as to cause the rope or cable to frictionally engage the drive-wheel and rotate the same to actuate the shaft and indicator.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein 'like numerals ofnrefuerence indicate corresponding parts throughout the several views, in which-f Figure 1 isa detail side elevation of my improved measuring device, showing the same in an operative position with the rope or cable in dotted lines. Fig. 2 is a top plan View of the same.

To put my invention into practice., I provide asuitahle frame or support l, which carries a handle 2 and a hub 3. Journaled in this hub 3 is an operating-shaft4, which extendsinto the casing of the indicator or register 5'. This indicator or register maybe of any approved vform `of construction which operates with a shaft extending into the same to actuate the mechanism. The casing of V.the indicator is preferably provided with a `to form a roughened surface for engagement Awith the rope and prevent the slipping of the latter upon the wheel. The frame or sup- 'port l carries an upwardly-extending arm 8,

to which is pivotally secured a bracket-arm 9, this bracket-arm carrying at its lower end a short shaft or axle upon which is jouirnaled the pulley-wheel l0. This pulley-wheel is normally held in contact with the drive-wheel 7 by a spring l1, which is connected to lugs 12 14, carried by the bracket-arm 9 and hub 3, respectively. The ropeor cable l5 is adapted to be placed between the wheels 7 and l0, as shown in the drawings, and to so insert this rope or cable the pulley-Wheel is pulled outwardly away from the wheel 7, the` spring` serving tonormally hold the pulley-wheel in engagement with the rope when thelatter is in position between the wheels.

When measuring, the device is usually applied to the sand-bailer rope or cable. When the sand-bailer has been lowered to the bottom of the well and the rope or cable is drawn taut, the operator can readily tell by grasping the `rope by the hand the exact time" at which the bailer is freeffrom the bottom of the' Well and its entire weightis on the rope or cable. Previous to this he has the device in position, so that when the rope is grasped ICO ' ister as the rope ascends, and thus determine register 5. By this means the operatormay observe the movement of the indicator or regthe exact depth of the Well.l

In the practice of my invention it Will be observed that various changes may be made in the detailsof construction Without departing from the general spirit of my invention.

Having fully described my invention, what I claim as nevv,`and desire to secure by Letters Patent, is

l. In a device for measuring the depth of y`wells, a frame Ihaving a handle secured to onel end thereofand a shaft journaled in the other end,one end of said shaft extending into the casing -of 4a register for the purpose of operating the register, a drive-Wheel rigidlymounted on said shaft, an upwardly-extending arm secured to the frame, a downwardly-extending bracket-arm pivotally secured to the upper end of said first-named arm,a pulleyjournaled in the lower extremity of said bracket-arm between which and said drive-wheel the rope passes, and a spring connec'ed to said bracket-arm for normally holdvvosges 'casing of the register, for the purpose of operating the register, an arm carried by the hub-and extending above said drive-Wheel, a bracket-arm pivotally secured to said arm and carrying a revoluble pulley in alnement with said drive-Wheel, lugs carried by the hub and the bracket-arm, and a spring connected to said lugs for holding the rope between said drive-wheel and pulley, substantially as described.

In testimony whereof I affix my signature in the presence of two Witnesses.
